I'm on ubuntu 12.04 kernel 3.2.0-53-generic. Just deployed ceph 0.80.5. Creating pools & images work fine, but getting this error when try to map a rbi image or mount cephfs: rbd: add failed: (5) Input/output error I did try flipping crush tunables instructed at http://ceph.com/docs/master/rados/operations/crush-map/#tunables, but still no luck. Anyone had the same problem or fixes? Thanks. -------------- next part -------------- A non-text attachment was scrubbed...
